0.3.1-alpha

• upgrade prop-types dependency (#20)
• use :static-properties instead of :class-properties to pass :childContextTypes (#20)

Derivatives 0.3.0

• ⚠️ Breaking derivatives-pool now returns the record instead of a map with the get! and release! functions. If you did not directly call the derivatives-pool function (and used the Rum mixins) this should not affect you. (e813f1ddfd7)
  • To upgrade replace uses of the get! and release! functions with their pendants in org.martinklepsch.derivatives (same names) and pass the derivatives pool record that is now returned by derivatives-pool as first argument.
  • Sorry for this breakage I hope it does not affect too many. 🙌
• Improvement depend on cljsjs/react-proptypes for React 16 compatibility (#18)
• Bugfix with a spec like {:db [[] (atom {})]} it was not possible to get ahold of the :db atom. (64efb6f3)

0.2.0: Performance and improved ergonomics

• New Feature Implement own derived-value that can be disposed, which will remove watches on sources (atoms or other watchable things) PR #2

• New Feature Extend Rum drv mixin to accept multiple arguments PR #5 & PR #8.
  Previously you called d/drv multiple times:

    (rum/defcs block < rum/reactive (d/drv :product/page) (d/drv :product/images) (d/drv :product/text) 
      [state]
      (let [page (d/react state :product/page)
            images (d/react state :product/images)
            text (d/react state :product/text)] 
        ...))

  Now it is possible to pass multiple keywords to the same function
  with the same result as multiple invocations. Also there is a new
  function react-all that can be used to dereference multiple or all
  known derivatives at once:

    (rum/defcs block < rum/reactive (d/drv :product/page :product/images :product/text)
      [state]
      (let [{:keys [:product/text]} (d/react-all state)]
        [:p text] ,,,))

    (d/react-all state) -> {:product/page 'val :product/images 'val :product/text 'val}
    (d/react-all state :product/page) -> {:product/page 'val}

• Internal The sync-derivatives! function and the
  DerivativesPool constructor now receive an extra argument
  watch-key-prefix that helps avoiding conflicts when creating
  multiple pools from a single source atom with specs that have
  overlapping keys. See
  #10 for
  details.

• Bugfix Fix wrong assumption in tests that would cause them to fail when a spec
  contains more complex keys: 37cda80

• Bugfix Fix issue where sync-derivatives! would fail if spec keys don't implement IFn b5f9545

Tests & Refactor

• add tests
• implement build in terms of sync-derivatives
• add assertions that spec is a map
• when checking if something is a function to use to derive a new
  value or if it is a source we now use (implements? IWatchable x)
  instead of (fn? x)
• refactor pooling implementation to allow testing of internals
• Rum mixins: simplifiy keys used in childContext to be strings
• Rum mixins: make sure the token is correctly passed to get! and release! functions
